Indignant now was Spain, objecting to the new ownership by the United States, and asserting that by the terms of the bargain with France that government had promised not to dispose of the province to any other nation. But this evidently had made no difference to Napoleon.

Not until November 30, of 1803, while Captain Lewis was on his road from Kaskaskia to St. Louis and Captain Clark was toiling with his keel-boat up from the mouth of the Ohio (both captains thinking that they had a clear way ahead), was the Spanish flag in New Orleans hauled down, and the French flag hoisted. On December 20 the representative of the French government there, Monsieur Pierre Clement Laussat, and his men, saluted the hoisting of the Stars and Stripes, formally delivered Lower and Upper Louisiana to the United States.

Nevertheless, Lieutenant-Governor Delassus, of Upper Louisiana, waited for official instruction. Distances were great, he wished to receive orders what to do. In St. Louis Captain Lewis waited; in the camp at Wood River Captain Clark waited; the Missouri froze over and they could not go on anyway.

Christmas was celebrated, and the memorable year 1803 merged into the new year 1804. Finally, by letter, date of January 12, 1804, from Monsieur Laussat at New Orleans, Lieutenant-Governor Delassus was notified that dispatches were on the road to Captain Amos Stoddard, of the United States Artillery, and commanding at Fort Kaskaskia, empowering him to represent France at St. Louis and take over from Spain the district of Upper Louisiana. He was then to turn it over to himself as representative of the United States.

On February 25 Captain Stoddard announced that he was ready to receive Upper Louisiana in the name of France. March 9 was set as the day. Captain Lewis was invited to be present at the ceremony, as an official witness. Captain Clark probably came over; perhaps some of the men, for all the countryside gathered at the great event.

A number of Indians from up the Mississippi and up the Missouri, and out of the plains to the west, had witnessed the ceremony of transfer. They did not understand it all. They said that the United States had captured St. Louis. On March 12 their good friend, Lieutenant-Governor Delassus, issued an address to them, explaining that now they had a new father, and he introduced to them the new United States chiefs who had come—Captain Stoddard and Captain Lewis.

But the Delawares, the Sacs, the Osages, and others—they still were dissatisfied, and especially the Osages. Captain Lewis was particularly anxious to please the Osages, for they were the first of the powerful tribes whom he might encounter, up the Missouri. He tried to talk with the chiefs in St. Louis; by a trader sent a letter on to the Osage village, asking the head chiefs to meet him at the river and exchange peace presents.

Beyond the Osages dwelt the Otoes, the Missouris, the ’Mahas (Omahas), the Sioux, the Arikaras, the Mandans, the Minnetarees; and then, who could say? Few white men, even the French traders, had been farther. How would all these tribes, known and unknown, receive the strange Americans?

Spring had come, the ice was whirling down, in rotted floes, out of the north, the channel of the crooked Missouri was clearing, and every man in the expedition was keen to be away, following the honking geese into this new America over which the flag of the United States waved at last.

Now the expedition had grown to full strength. There were the two captains; the fourteen soldiers enlisted at Pittsburg, Fort Massac and Fort Kaskaskia; the nine Kentuckians, enrolled at Mulberry Hill near Louisville; George Drouillard (or Drewyer, as he was called), the hunter from Kaskaskia who had been recommended by Captain Clark’s brother the general; Labiche and one-eyed old Cruzatte, French voyageurs or boatmen engaged by Captain Lewis at St. Louis; nine other boatmen, and Corporal Warfington and six privates from the Kaskaskia troops in St. Louis, who were to go as far as the next winter camp, and then return with records and trophies; and black York, Captain Clark’s faithful servant, who was going just as far as his master did.
